According to the monthly 1st MAW Command Chronologies for March-July 1968, the assigned call sign was "Reenlist". It remained the "official" call sign at least through Feb 1969. When did "Scarface" return, or was it used all along?
On the list of tailcodes/call signs (I didn't come up with the call signs) "Dixie Cup" and "Eagle Claw" are shown for 367. When were these used?
